How many grams of NaCl can be dissolved in 100g of water at 90 degrees Celsius?
7
How many grams are in 90 milligrams?
There are 1000 milligrams in a gram. To convert, you divide by 1000. 90/1000 is 0.09 grams.
How much Na Cl will dissolve in 350 g of water at 90 degrees Celsius?
The answer is 134,645 grams of NaCl.
How many grams of water can be prepared from 5moles of hydrogen at standard conditions?
Balanced equation. 2H2 + O2 --> 2H2O 5 moles H2 (2 moles H2O/2 mole H2)(18.016 grams/1 mole H2O) = 90 grams of water ===============
How many moles are in 9.8 grams of Calcium?
Strictly, elements such as calcium do not have "moles", but the corresponding term, for Avogadro's Number of atoms of an element, is called "gram atomic mass". For calcium, this number is about 40.08 grams. Therefore, 9.8 grams of calcium is about 9.8/40.08 or 0.24 gram atoms, to the justified number of significant digits.
How many kilograms are in 90 grams?
90 kg = 90 000 gTo convert from kg to g, multiply by 1000.
What is the molality of a solution of 90 grams of glucose C6H12OSUB6 dissolved in 800 grams of water?
first determine the number ofmoles dissolved in given solution then .5 moles moles dissolved in 800g. as comparison with 1000g of water, we know 100g of water dissolve only.1 moles of a glucose so we .7moles of glucose dissolve in 800g.
Is NaCl decreases when heated to 90 degree C?
No, NaCl is not affected by such temperatures.
What is the density of an object that has a volume of 90 cubic centimeters and a mass of 360 grams?
Density= Mass (in grams)/ Volume (in milliliters) So convert to the correct units.. 1 cc= 1 mL, so 90 cc= 90 mL Density= 360 g/ 90 mL = 4 g/mL
How many grams of calcium carbonate are required to prepare 50.0 g of calcium oxide?
This is a mass stoichiometry problem. Start with the balanced equation: CaCO3 --> CaO + CO2. Do a conversion from 50g CaO to moles: 56g/1mol=50g/x, x=.9 moles. The equation is balanced as written, with all coefficients understood to be 1. So: .9 moles CaO means .9 moles CaCO3. Do another conversion from moles to grams: 100g/1mol=x/.9 moles. Solve for x to get 90 grams. (56g=molar mass of calcium oxide; 100g=molar mass of calcium carbonate.)
How many grams of of NaOH are required to prepare 200 mL of a 0.450 M solution?
Molarity = moles of solute/volume of solution 0.450 M = m/200ml = 90 millimoles, or, what we need; 0.09 moles 0.09 moles NaOH (39.998 grams NaOH/1 mole NaOH) = 3.60 grams of NaOH needed
How many grams does 90.25 kilograms equal?
90.25 kg = 90 250 gTo convert from kg to g, multiply by 1000.
